Quite reproducible. Once "something" trigger the hang, no matter how
I reset the system, it'll still hang at suspend. And at other times,
it just worked. I tried many things, but it seems if I go back to use
an earlier version (2.6.37 works perfectly for suspend-to-disk/mem),
then switched back to the newer broken version, it'll work for a few
cycles before hanging at suspend-to-disk.

I guess it could be CPU hotplug, and may be that thinkpad-acpi is
triggering the broken cpu hotplug to fail.
